General description
Montmorillonite is a layered clay mineral (2:1 phyllosilicate) that belongs to a class of the smectite group. It is a naturally abundant material and is chemically modified by the cation-exchange method for the preparation of polymer nanocomposites.
Application
Montmorillonite has been used as:
It can also be used:
- A nanofiller to improve the mechanical properties of poly(vinyl alcohol) (PVA) film for potential usage in packaging applications.
- A catalyst in the conversion of polar and non-polar algae oil lipids to biodiesel.
It can also be used:
- As a nanofiller in the preparation of biopolymer based nanocomposites.
- In the preparation of Fe3+-montmorillonite, a solid acid catalyst for the synthesis of xanthenedione derivatives.

Layer aluminosilicates catalyze reactions in numerous ways. They stabilize high-energy intermediates. They can store energy in their lattice structures and can release it in the form of chemical energy. They can catalyze redox reactions and can serve as photocatalytic devices.
